Chapter 12, Problem 12.77P

Interpretation Introduction

Interpretation:

The difference between an amorphous solid and a crystalline solid on the macroscopic and molecular levels is to be determined. Also, the example of an amorphous solid and crystalline solid is to be given.

Concept introduction:

The phase is defined as the physical state of a substance. The properties of a phase are determined by the interaction of the potential energy $\left(E_p\right)$ and kinetic energy $\left(E_{\text{k}}\right)$ of particles. There are three major phases as follows:

1) Solid

2) Liquid

3) Gas

Solids can be classified into two types as follows:

1. Crystalline solids

2. Amorphous solids
